Description Jan Vesely 2017-08-08 02:11:51 UTC

dev-lang/rust includes bundled llvm-4.0.1 (presumably with patches).

I understand that support for system-llvm was dropped,
but the bundled version is configured using:
"-DLLVM_TARGETS_TO_BUILD=X86;ARM;AArch64;Mips;PowerPC;SystemZ;JSBackend;MSP430;Sparc;NVPTX;Hexagon"
I don't know how those targets were selected, but I'm pretty sure that it won't need most of those targets on my machine.

Fixed in dev-lang/rust-1.26.0. The ebuild now uses LLVM_TARGETS to decide what targets to build.

    dev-lang/rust: version bump to 1.26.0
    
    Use LLVM_TARGETS to decide which targets to build for bundled LLVM. Use
    xz-compressed tarballs where possible to limit bandwidth/storage.
